JSON ファイルからのデータのエコーに問題があります。

<?php
$url = file_get_contents("http://api.erpk.org/citizen/profile/3121752.json?key=Yn3AsG80");
$json = file_get_contents($url);
$data = json_decode($json, true);
echo "<pre>"; var_dump($data); echo"</pre>";
?>

上記は、私が使用している私のphpファイルで、以下に示すようにJSONを出力します:

私の問題は、すべてのデータを一度にロードすることだけであり、それぞれをエコーし​​たいだけです。JSON の経験がないため、エコーする変数がわかりません。

あなたがアクセスできるJSONを介して

JSON Version : http://api.erpk.org/citizen/profile/3121752.json?key=Yn3AsG80
XML Version : http://api.erpk.org/citizen/profile/3121752.xml?key=Yn3AsG80

私が達成したいことは次のとおりです。

  1. 出力なしで JSON または XML をロードして、ECHO を使用して、PHP ファイルで表示したい場所にデータを配置できるようにします。
  2. JSON または XML データのそれぞれを ECHO します。

試行するたびに、オブジェクトではないというエラーが表示されます

あなたは を誤用file_get_contentsしているので、それがあなたの問題だと思います。その URL からデータを取得するには、次の最初の行だけを使用します。

$url = 'http://api.erpk.org/citizen/profile/3121752.json?key=Yn3AsG80';

とにかく、JSON データセットを指定して短いプロファイルをエコーするコード スニペットを次に示します。

nameおよび のような第 1 レベルのフィールド、およびbirthのような第 2 レベルのフィールドrank\level、rank\nameそして最後に のようなフィールドの動的セットにアクセスする方法を示しますmedals。

<?php
$json = '{"id":3121752,"name":"SnowderBlazer","birth":"2010-04-10","avatar":"http://static.erepublik.net/uploads/avatars/Citizens/2010/04/10/4bb9a72cc291faaaf7af8e78ed0a8509_100x100.jpg","online":false,"ban":null,"alive":true,"level":97,"experience":360391,"strength":42859.62,"rank":{"points":437120237,"level":64,"image":"http://www.erepublik.com/images/modules/ranks/god_of_war_2.png","name":"God of War**"},"elite_citizen":false,"national_rank":1,"residence":{"country":{"id":65,"name":"Serbia","code":"RS"},"region":{"id":198,"name":"Midi-Pyrenees"}},"citizenship":{"id":65,"name":"Serbia","code":"RS"},"about":"Voters Club Moderator\ncatch me on #voters @Rizon\nIRC Nick : Snowderblazer OR Snowderblazer[BNC]\norder herehttp://erepublik-market.com/voters/newOrder.html?adp=1549866\n[ident:9vrwQZB9]","party":{"id":2479,"name":"Ujedinjena eSrbija","role":"Party Member"},"army":{"id":1980,"name":"Legija Stranaca Elite","role":"Commander","created_at":"2012-05-26","avatar":"http://static.erepublik.net/uploads/avatars/Groups/2012/05/26/f80bf05527157a8c2a7bb63b22f49aaa_medium.jpg","rank":"Commander"},"newspaper":{"id":241367,"role":"Press director","name":"M.A.D.S News"},"top_damage":{"damage":215238312,"date":"2013-05-16","message":"Achieved while successfully defending Basilicata against Italy on day 2,004"},"true_patriot":{"damage":3021790429,"since":"2012-04-26"},"medals":{"battle_hero":248,"campaign_hero":98,"congress_member":9,"country_president":0,"hard_worker":36,"media_mogul":5,"mercenary":1,"resistance_hero":2,"society_builder":0,"super_soldier":171,"top_fighter":3,"true_patriot":43},"hit":14924}';

$data = json_decode($json, true);

echo "Name: {$data['name']}\n";
